Enum Argument 

pub enum Argument {
    Imm(isize),
    Reg(Register),
    Label(String),
}

A high-level representation for an argument given to an instruction. The Argument::Imm variant may represent any of the following concrete arguments: uimm4, imm4, uimm8, imm8. An op2 or uop2 is considered to be either a register or a imm4, uimm4 respectively.

Variants

Imm(isize)

Reg(Register)

Label(String)

Implementations

impl Argument

pub fn parse_int(arg: &str) -> Result<isize, ParseIntError>

Parses an int, potentially in hex or binary formats.

pub fn parse(arg: &str) -> Option<Self>

Parses an argument.

impl Argument

pub fn apply<F: FnOnce(&mut isize)>(&mut self, f: F)

Applies an arithmetic manipulation to an argument if it is an immediate.

Trait Implementations

impl Clone for Argument

fn clone(&self) -> Argument

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Codable for Argument

fn encode(&self) -> u16

Encodes the instruction or portion thereof.

fn decode(value: u16, mode: Mode) -> Option<Self>

Decodes the instruction given the current mode of execution.

impl Debug for Argument

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Argument

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Argument

fn eq(&self, other: &Argument) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Argument

impl StructuralPartialEq for Argument
